how long should I expect a grow tent to last?

Not too long ago I started using a Gorilla "Lite" 2'x4' tent. It seems pretty sturdy, but I'm just wondering what the life expectancy of one is? Are the zippers the first thing to go? The stitching? Can they last for years with daily use?

had mine in use just over 2years and a mates been using it the last 1.5years and still like new

Excellent, that's good to hear!
